Primary Outcome Measures:
  • Pharmacodynamics (serum & tissue biological markers; CCR5 receptor occupancy) [ Time Frame: 8 weeks ]
    Change in CCR5 properties; change in inflammatory markers in blood and colon.

  • Clinical Response [ Time Frame: 8 weeks ]
    Decrease in Mayo Score and rectal bleeding.


Secondary Outcome Measures:
  • Type, frequency, and severity of adverse events [ Time Frame: Through 8 weeks after the last dose of study agent ]
  • Clinical response [ Time Frame: 4 weeks ]
    Decrease in Mayo Score and rectal bleeding.

  • Clinical remission [ Time Frame: 4 weeks & 8 weeks ]
    Decrease in Mayo Score and no rectal bleeding or colon friability.

  • Mucosal healing [ Time Frame: 4 weeks & 8 weeks ]

Enrollment: 0
Study Start Date: December 2011
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: HGS1025 2 mg/kg Biological: HGS1025
2 mg/kg of HGS1025 administered by IV infusion on Day 0, 14, 28 and 56, and then every 28 days thereafter if patient achieves clinical response
Experimental: HGS1025 10 mg/kg Biological: HGS1025
10 mg/kg of HGS1025 administered by IV infusion on Day 0, 14, 28 and 56, and then every 28 days thereafter if patient achieves clinical response
Placebo Comparator: Placebo Drug: Placebo
Placebo administered by IV infusion on Day 0, 14, 28 and 56. Subjects receiving placebo during the first 8 weeks of treatment will be given the option to receive HGS1025 10 mg/kg in the continuation phase of the study.
